The electrocatalytic reduction of CO2 to produce sustainable fuels and chemicals is attracting great attention. Cu-based catalysts can lead the production a range different molecules, interestingly product selectivity strongly depends on preparation history, although it not fully understood yet why. We report novel strategy that allowed us prepare Cu nanoparticle carbon with similar morphologie...

Selective dehydrogenation of ethanol to acetaldehyde has been considered as an important pathway produce due the atom economy and easy separation hydrogen. Copper catalysts have attracted much attention high activity Cu species in O-H C-H bonds oxidative cleavage, low process cost; however, size nanoparticle is difficult control since it easily suffers from metal sintering at temperatures. In t...

In this study, novel SiO2- and Al2O3-supported Cu-Fe catalysts are developed for selective hydrogenation of 2-methyl-3-butyne-2-ol to 2-methyl-3-butene-2-ol under mild reaction conditions. TEM, XRD, FTIR studies adsorbed CO TPR-H2 performed characterize the morphology, nanoparticle size, particle distribution, as well electronic state deposited metals in prepared catalysts. The deposition Fe Cu...

Stable coinage metal nanoparticles (NPs) have been synthesized individually in an aqueous alkaline solution from the corresponding metal salts as precursors using the condensation product (CP) of salicylaldehyde and triethylenetetramine as a reagent. Silver and gold NPs are obtained with and without light illumination but UV irradiation is essential for Cu(0)NP formation. During nanoparticle fo...

Stable oil-in-water nanoemulsions were generated by ultra-high-pressure homogenization (UHPH) at 140 and 210 MPa for use as nano-vesicular vehicles (NVV) to carry hydrophobic generally recognized safe (GRAS) curcumin (CU) whey protein isolate (WPI) in aqueous nutraceutical systems. Curcumin was used its antioxidant activity participation the Michael reaction with nucleophiles pHs above 8.0. Two...

Joule heating studies on nanoparticle/nanocarbon hybrid aerogels have been reported, but systematic investigations hydrotalcite-derived catalysts supported onto reduced graphene oxide (rGO) are rare. In this study, Cu-Al2O3 nanoparticles were incorporated into a porous and multifunctional rGO aerogel support for fabricating electrically conducting Cu-Al2O3/rGO aerogels, their properties investi...
